That story has been around for many years and seems to be accepted as true. The way I understand it is in 1967 the car was just RPO Z 28 but did not have the Z/28 emblems on it. In order to race in Trans Am the SCCA homologating requirement was 1000 cars. Chevy built 602 1967 302 Camaros but the SCCA let them slide by counting the 350cu in Camaro to make the 1000 unit total. In 1968 they wanted management (Estes) to approve the promotional ad campaign advertising the car as the Camaro Z/28. Turned out to be another one of Vinnce Piggins's good ideas.
